Hello, I'm Joe.
Thank you for reading~
This post is only for DC treadmills, if it is an AC treadmill fault code, please contact us.
DC treadmill: The motor is DC voltage, and most of them are home treadmills.
AC treadmill: The motor is AC/three-phase voltage, mostly commercial treadmills.

E01:  95% are "speed sensor failure"/"communication failure"/"control board failure". It is very rare that the control board is damp.

Solution:
Please replace the treadmill speed sensor/check cable.
To order a new speed sensor:
To order a new controller:

E02: The control board is faulty.
90% is the "lower controller" failure, 10% is the display motherboard failure. The main cause of the failure: the output of the motor is unstable, which leads to the damage of the "diode/power tube".

Solution:
1. First check whether the motor is normal.
2. It is recommended to order a new control board. Please provide the old controller model/photo and contact me.

E03: When E03 appears on your treadmill, there are 2 reasons for the failure.
1. When you start the treadmill, the motor will rotate briefly for a few seconds. It is "speed sensor failure".
2. When you start the treadmill, the motor does not rotate, and the console displays E03. It is "control board failure".

solution:
1. Test the motor of the treadmill first to check whether the motor is normal. The motor is normal, please replace the "speed sensor".
2. Please replace the "display motherboard", please provide me the old "controller" model/photo, I can provide you with the motherboard.

E-4: current overload protection.
If you install a new board, E-4 appears. The power value of the controller needs to be calibrated.
If "E-4" and "E-2" appear at the same time, it is most likely that the motor and the control board are damaged at the same time.

solution:
Test whether the motor is normal, test method:

E-6: Control board failure/communication failure/incline failure.
Simultaneous appearance of "E-6" and "E-7" is an incline motor failure, and the incline motor needs to be checked.
Other E-6, most of them are LCD motherboard or lower controller failure.

solution:
Check the incline motor: connect the "red + white" or "black + white" cable directly to the AC power supply, check if the incline motor is raised or lowered.
If it is not the incline function failure, please replace the LCD main board or controller with a new one.
If you are not sure about the model, you can contact us.

E-7: The safety key is not placed on the console/the "magnetron" of the console is damaged/the built-in magnet of the console falls off/the incline motor may also be faulty.

solution:
Check whether the safety key is placed / check whether the incline motor is normal,
To order an incline motor:

E-8: Most of them are motor failures.

solution:
Test the motor:
